Surgical Resection of Pancreatic Hepatoid Carcinoma Followed by Combined Transarterial Chemoembolization and Immunotherapy: A Case Report

Pancreatic hepatoid carcinoma (HC) is a heterogeneous tumor with high degree of malignancy and poor prognosis, which display cytological and/or structural features of focal hepatocellular carcinoma (HCC). For the low incidence and atypical clinical symptoms, it is possible to be diagnosed as pancreatic cancer before operation, and mainly depending on the pathological examination. To the best of our knowledge, surgery combined with radiotherapy and chemotherapy is the common treatment of pancreatic HC. However, the curative effect and prognosis is poor. We report a case of 44-year-old woman with pancreatic HC treated with PD-1 receptor inhibitor and transarterial chemoembolization, whose clinical symptoms and laboratory indexes are significantly improved after treatment.
